[China Aluminum Network] All aluminum production is based on the Hall-Heroult method. Alumina prepared from bauxite is dissolved in cryolite and the electrolyte, and several fluoride salts are added between them to manipulate the electrolyte temperature, density, resistivity, and solubility of aluminum. Then, a current is passed to electrolyze the melted alumina. In this way, oxygen is generated on the carbon anode and reacts with the latter, while aluminum is collected as a molten metal layer on the cathode. The metal that has been separated can be removed from the crucible by siphon or vacuum at a regular time, and then the liquid is transferred to a forging facility and cast into ingots.
